Abstract
Tertiary ether amines were prepared and their surface active properties were discussed.The tertiary ether amines were synthesised as follows.N, N-di (alcoxy ethyl) ethanol amine (I) was prepared by N-alkylation of monoethanolamine with 1-chloro-polyoxaalkane.Tri-alcoxy ethyl amine (II) having the three same chaines of alcoxy ethyl group was prepared by the reaction of 1-chloropolyoxaalkane with the alcoholate of (I).Surface tension, foaming property, wetting, dispersing and emulsifying power of the aqueous and acidic solution of these tertiary amines were determined. It was observed that the aqueous solutions of the amines had very low foaming, good wetting and dispersing power.
